What's good: Get ready for a completely new and exciting solitaire experience with Kuyi Mobile's flagship game for the iPhone and iPod touch! If you thought classics were best left as is, Card Drop will prove otherwise. Essentially, the gameplay builds on solitaire's card stacking concept, but this predictable formula has been sprinkled with some innovation for a more fast-paced and challenging time. When you start a game, you'll notice five random cards at the bottom - your goal is to take these and stack them in ascending or descending order on the four columns of continually falling cards. Don't see a possible match? Just tap the descending card to discard it and get a new one. Once a card reaches the edge of the screen, you're given points based on how tall you were able to make your pile, while new cards automatically replace ones that have been used or dropped. To add to the exhiliaratingly accelerated feel, a liquid timer on the right will keep you on your toes as you tap as fast as you can to reach the highest score possible before it drains out. This makes it quite obvious that the game requires dexterous fingers, a quick eye, and lighting fast coordination. You can even earn fun achievements like Card Drop Whiz or Combo Maniac, and with practice, will soon be creating combo after combo to fill the blue bar, extend your time, and hopefully snag a spot in the leaderboards. Finally, capping it all off are the crisp, professional graphics and a soundtrack that manages to match the game's speed and yet is easy on the ears. We think this refreshingly original app is a great buy for $ 1.99, and you probably will too! Check it out on the AppStore, you'll be hooked in no time.

Suggestions for improvement: There could be more gameplay features or levels to make things more interesting and prevent the game from becoming too repetitive.
